SNP BINDING SITE FOR microRNAs IN HLA-G

Analysis of microRNA interference with HLA-G expression identified the HLA-G 3'UTR SNP+3142G/C that disrupts a target for microRNA 148 (miR148) and is associated with asthma. The polymorphism is associated with protection from (or susceptibility to) moderate to severe viral infection in the first 3 years of life and asthma by age 6, with an interaction with mother's affection status (asthma). A SNP in the 3'-Untranslated Region (UTR) of HLA-G influences the targeting of 3 micro(mi)RNAs to the gene. Allele-specific targeting of these miRNAs accounts, at least in part, for the association between HLA-G and the risk of asthma.
